Abstract
Purpose
To review current knowledge on clinical outcomes and peri-operative complications of prostatic arterial embolization (PAE) in patients treated for lower urinary tract symptoms (LUTS) related to benign prostatic obstruction (BPO).
Methods
A systematic review of the literature published from January 2008 to January 2015 was performed on PubMed/MEDLINE.
Results
Fifty-seven articles were identified, and four were selected for inclusion in this review. Only one randomized clinical trial compared transurethral resection of the prostate (TURP) to PAE. At 3 months after the procedure, mean IPSS reduction from baseline ranged from 7.2 to 15.6 points. Mean urine peak-flow improvement ranged from +3.21 ml/s to +9.5 ml/s. When compared to TURP, PAE was associated with a significantly lower IPSS reduction 1 and 3 months after the procedure. A trend toward similar symptoms improvement was however reported without statistical significance from 6 to 24 months. Major complications were rare with one bladder partial necrosis due to non-selective embolization. Mild adverse events occurred in 10 % of the patients and included transient hyperthermia, hematuria, rectal bleeding, painful urination or acute urinary retention. Further comparative studies are mandatory to assess post-operative rates of complications, especially acute urinary retention, after PAE and standard procedures.
Conclusion
Early reports suggest that PAE may be a promising procedure for the treatment of patients with LUTS due to BPO. However, the low level of evidence and short follow-up of published reports preclude any firm conclusion on its mid-term efficiency. Further clinical trials are warranted before any use in clinical practice.
